Unfortunately, limitations of the browser used by Answers.com means that we cannot see most symbols. It is therefore impossible to give a proper answer to your question. Please resubmit your question spelling out the symbols as "plus", "minus", "times", "equals".
There is no sign (plus or minus) before the final 1.
If p, q, r, ... are the roots of the equations, then (x-p), (x-q), (x-r), etc are the factors (and conversely).
The equation x2+5x+6=0 simplifies to (x+2)*(x+3)=0. From this you can determine the roots by setting x+2 and x+3 equal to zero. The roots of the equation are -2 and -3.
It has two complex roots.
There are 2 roots to the equation x2-4x-32 equals 0; factored it is (x-8)(x+4); therefore the roots are 8 & -4.
Calculus was created in order to calculate volume and area. Everything in our world is not able to be measured by straight lines and 90 degree angles. Its roots can be traced back the the ancient Egyptians. You can read more about the history of calculus at the link provided below.
There are none because the discriminant of the given quadratic expression is less than zero.
zero
The graph of a polynomial in X crosses the X-axis at x-intercepts known as the roots of the polynomial, the values of x that solve the equation.(polynomial in X) = 0 or otherwise y=0
x = -2.5 + 1.6583123951777ix = -2.5 - 1.6583123951777iwhere i is the square root of negative one.
Yes.
It is difficult to tell because there is no sign (+ or -) before the 5. +5 gives complex roots and assuming that someone who asked this question has not yet come across complex numbers, I assume the polynomial is x2 -3x - 5 The roots of this equation are: -1.1926 and 4.1926 (to 4 dp)
The "roots" of a polynomial are the solutions of the equation polynomial = 0. That is, any value which you can replace for "x", to make the polynomial equal to zero.
According to the rational root theorem, which of the following are possible roots of the polynomial function below?F(x) = 8x3 - 3x2 + 5x+ 15
You can find the roots with the quadratic equation (a = 1, b = 3, c = -5).
-2.5 + 1.6583123951777i-2.5 - 1.6583123951777i
of the rational function p(x)/q(x). These roots are the values of x that make the numerator, p(x), equal to zero. In other words, they are the solutions to the equation p(x) = 0.
A third degree polynomial could have one or three real roots.
